高强度船用钢抗活性破片毁伤装甲防护试验
Experimental investigation of high-strength ship steel plate protection against reactive fragment impact
摘要
Abstract
[Objectives]This paper investigates the failure mechanism and protective performance differ-ences of 10 mm thick high-strength ship steel when it is subjected to penetration-deflagration by reactive and inert fragments respectively.[Methods]A 12.7 mm caliber ballistic gun is used to shoot cylindrical frag-ments at high-strength ship steel.Reactive composite fragments and inert steel fragments with a similar dens-ity and quality interact with the high-strength steel target.The fragment damage mechanisms,target failure modes and energy absorption and release characteristics are then compared,and naval standard ballistic limits V50 for the ship steel target are obtained under different fragment damage conditions.[Results]The ballist-ic limits V50 of the ship steel target against inert and reactive fragments are 807 m/s and 874 m/s respectively.The perforation ability under reactive fragments is superior to that under inert fragments,but its expansion ability under reactive fragments is inferior to that under inert fragments.The impact process of reactive frag-ments is accompanied by strong firelight coverage,and their total penetration-deflagration energy is higher than the single penetration kinetic energy of inert fragments.[Conclusion]The experimental results of this study can provide data support and guidance for the design of ship protective structures and the application of active damage technology.关键词
